K Yairi Guitars Serial Numbers
I have a 1985 Alvarez Yairi model DY-62 and serial 58006. It has stereo pickups where you can run two cables from guitar with two volume pots and two eq pots. The lower front of the guitar is inscribed with the signature of K. It is in good condition with a few dings on the body and a little fret wear. A discussion group for Alvarez-Yairi and K. Yairi guitar enthusiasts. I just picked up a used Alvarez by Kazuo Yairi dread guitar, Serial Number 63721. Prablema maraljnaga vibaru u tvorah v bikava.
Take it slow. Buy her a set of strings first, and maybe she will give you her number. But seriously, I think it's hard to definitively date Alvarez guitars from that era because the company itself doesn't have accurate records. This site includes some good general info if you scroll down to the Alvarez section: Based on the type of label you have with the eagle, and the Made in Japan, I would have guessed your guitar was built in the late 70's or early 80's. I believe after 1985 or so their production moved to Korea (and later China for budget guitars). If Alvarez says mid-70's based on the serial number, that's probably the best you're going to get.
I'm by no means an expert on Alvarez acoustics, but I hope that info offers at least some help. O.K., crappy pictures of a beautiful but well used guitar.
This has been my number one kick back and play guitar for over 20 years. Laminate construction. Spruce top and Tree of Life inlay. The double A as opposed to the AY logo shows it s definately an Alvarez and not a Yairi. Rosewood back and sides. Yes, there are screws missing, but it actually stays in tune.
The reason I got the urge to date it is because I have finally decided to restore it. I'm starting to lose the binding on the neck (as you can see in the last shot) but I love it too much to replace it. I too have a similar Alvarez made in Japan, 4 digit model no. Mine is a 5059 autumn heringbone model and there is actually a production date on the tag in the sound hole of 1978. The tag is identical to yours as is the headstock logo inlay. Tuners are different however. Based on the similarities to yours I would date it around the same years, '77-'80.
I know the model name due to an Alvarez advertisement clipping that depicts the model I have. I too am getting ready to do some much needed TLC to mine as it has been my most loved acoustic for 20 years now. It was a gift from my mother who used it in a country band way back when.
These are great guitars that can be bought very cheaply when you can find them. Good luck with the search! Judging by the tag in the sound hole, headstock logo, and general construction of the guitar I would think it's definite made earler than '86. Mine has a tag identical to this one but the date 16 5 78 is stamped onto it and it also has the name of the person who inspected it stamed on it. Interestingly I did notice your guitar has a different truss rod construction than mine. Looks like yours adjusts from the head stock under the cover and mine is an allen adjustment through the sound hole. Don't know if they switched over to your style at a later date.
